fix(web): truncate long filenames in file list (no-preview state) (#3370)
When the design files preview pane was closed, a very long filename
would expand its `<td.df-cell-name>` and push the kind / mtime / menu
columns off-screen — the auto-layout `<table>` had no width
constraint on the cell, so the existing `text-overflow: ellipsis`
on `.df-row-name` never engaged.

The `:not(.no-preview)` overrides in `routines.css` already pinned
the row's children to `width: 100%; max-width: 100%` when a preview
pane was open, but the no-preview state — the one shown in the issue
screenshot — had no equivalent guard.

CSS:
- `.df-cell-name`: add `max-width: 0; min-width: 0` so the table
  cell collapses to its column allocation in auto-layout.
- `.df-row-name-wrap`: add `max-width: 100%`.
- `.df-row-name`: add `max-width: 100%; min-width: 0` so the flex
  child clamps to the wrap and the existing ellipsis engages.

JSX (DesignFilesPanel.tsx):
- Add `title={f.name}` (and the equivalent for directory rows and
  live-artifact rows) on `.df-row-name`. The browser surfaces the
  full filename on hover even when the visible text is truncated, so
  users can read the leading characters without opening the preview
  pane. `<DfPreview>` already renders the full name with
  `word-break: break-word`.

Closes #3260

Validation:
- pnpm exec vitest run tests/components/DesignFilesPanel.long-name-truncate.test.tsx
  → 3/3 passed (1 was red on main: title attr was absent)
- pnpm --filter @open-design/web test → 2501/2501 passed (260 files)
- pnpm --filter @open-design/web typecheck → green
- pnpm guard → green

Note: jsdom does not measure layout, so the truncation itself can't
be asserted directly. The specs encode the structural contract the
CSS depends on (cell / wrap / name nesting + the `title` attr) so a
JSX shape change won't silently regress the fix.
